[mythtv-users] HD PVR not starting

I am trying to set up MythTV 0.25-fixes on an Ubuntu 12.04 system, direct
from Ubuntu's repository. I have a Hauppauge HD PRV running firmware 1.7.1.
My video source is a DirecTV receiver connected with component cables and
SPDIF audio.

Outside of Myth, it "just works". I simply plugged it in and was able to
grab playable video with the command "cat /dev/video0 > test.ts". I had to
use v4l2-ctrl to change the input to SPDIF to also get sound, but that was
pretty simple.

Myth, however, refuses to start up the HD PVR. When I go to "Watch TV", the
HD PVR doesn't activate. After about 10 seconds of a black screen with the
channel banner at the bottom, I get a message saying a lock should have
been achieved by now, so I can wait longer or try changing the channel. The
receiver is already sending a channel (I can verify using the method
above), so I should have some video upon switching to live TV. There is a
little bar at the top of the screen that says "1: Component", so I think my
input setup is correct. Also, in the capture card setup, I have it set up
as an H.264 device. MythTV lists "Hauppauge HD PVR [hdpvr]" as the probed
info, so I think it is seeing the device correctly.

I ran the frontend with the -v option, and saw this in the output, which
may or may not be helpful:

Any ideas?
